问题 I have a JTextPane and when a user clicks a button, I want certain portions of the text to "hide" StyleConstants.setFontSize(style,0); StyleConstants.setForeground(style,textPane.getBackground()); accomplished this perfectly, however it is also raising the following error: Java[20425] : CGAffineTransformInvert: singular matrix. Is there a way to accomplish what I'm doing (set font size to 0) without getting this error? Thanks! 回答1: The TextPane logs different types of messages (order matters)

问题 I have a JTextPane that has pane.setEditable(false) which forces it to have a 'greyed-out' background color. After trying setBackground(Color.WHITE) (which doesn't work), I tried looking around the net for an answer but not managed to find one yet. Can anyone help me on this one please? 回答1: Note that for some Look and Feel like Nimbus that don't respect background property, you can use this code : private static class Painter extends javax.swing.plaf.nimbus.AbstractRegionPainter { private

Error with making text bold and colored in JTextPane

I am having an issue with changing the color of a selection of text that is a mix of bold and not bold. For example, if I have the text in the editor " bold text not bold text" and I highlight both words and try to change the color of the text, it changes the color and makes all of the text bold, instead of leaving the second word not bold. So I

JTextPane and empty filler space

由 試著忘記壹切 提交于 2019-12-11 19:29:02

Perhaps there is an easier way? 回答1: You can use setMargin() to set margin space between
